Abstract
A method of operating a lubrication system for a gas turbine engine includes pumping a lubricant from a supply conduit to a bearing compartment. A pressure differential in the bearing compartment. The supply conduit is evacuated in response to the pressure differential creating step. The supply conduit is refilled with the lubricant from a reservoir conduit fluidly joined to the supply conduit at a junction by gravitationally draining the reservoir conduit.
